Why do you think that King Affonso let the Portuguese enslave his subjects at first?

I believe that King Alfonso thought it was a good idea to enslave his subjects at first because it could help boost his wealth and the country's wealth without paying the people who actually did the work. He did not want lower-class people in his country because he wanted all the things he wanted in order to live a luxurious life.

In the letter below, why does the king now request regulations?

The King was finally hearing from all of his people that many of the people in Portugal were being taken away for slavery. He set guidelines because he realized many of the people were being enslaved for no reason at all.
